Abstract
Heterogeneous asymmetric catalysts using amino acids as chiral promoter were synthesized by attachment of amino acids such as l-glutamic acid and l-phenylalanine onto the hydrophilic part of hydrolyzed octadecyltrichlorosilane (OTS). The catalysts exhibited 12-18% enantiomeric excess (ee) for the asymmetric hydration of epoxycyclohexene to yield (1R,2R)-trans-1,2- cyclohexanediol and (1S,2S)-trans-1,2-cyclohexanediol.
